Once long ago an amazing empire held wealth and power. Its technology could not be rivaled. After a horrific battle it fell beneath the waves seemingly lost for all time. Not much more than a thousand years later did it return to seek vengeance. That vengeance would be the biggest war modern Equestria has seen yet.
